Andy Kyle, a 53-year-old man in Dartmouth City, Devon County, he sees a double rainbow above Kingwear - the name of a village near the seaport - when looking out the window of the office on April 19, Mirror takes believe.

When the sun's rays meet water droplets in the air, they will be bent (refracted) or bounced back (reflected). In the process, light is scattered into seven primary colors. Most of the light escapes and focuses into an arc on the opposite side of the sun. It is a first-class rainbow. The colors of the rainbow arranged in turn: red, orange, yellow, green, blue, indigo, purple.

But part of the light is bent once more in the drop of water, creating a quadratic rainbow when escaping.

If the light is bent three or four times, the third or fourth rainbow will appear. But after each reflection, the light becomes weaker and the rainbow is also dimmer. So people often see first and second grade rainbows, but rarely see the third and fourth degree rainbow.
